The invention discloses an unmanned aerial vehicle with pressurized fuel oil system. The unmanned aerial vehicle comprises a vehicle body, wings and an empennage, a fuel oil supply system and a control system are arranged in the vehicle body, the fuel oil supply system is controlled by the control system, and the unmanned aerial vehicle is characterized in that an engine air inlet rectifying device is arranged at the upper end of the rear portion of the vehicle body and comprises an air inlet channel and an air inlet fairing; the air inlet end of the air inlet channel is communicated with theair inlet fairing, the air outlet end of the air inlet channel is communicated with an air inlet of an engine cavity, an air inlet of the air inlet fairing is oblate and faces the advancing directionof the unmanned aerial vehicle, and the air inlet fairing is formed by gradually contracting and extending in an arc shape from the two sides of an unmanned aerial vehicle body to the center to the direction of an unmanned aerial vehicle head. Faults caused by turbulence due to unsmooth air intake of the engine are prevented; and meanwhile, the substantive technical problem of 'airlock' of the oilsupply pipeline is also solved.
